As Hibiki is spending more and more time fighting the Noise, it means less time for her studies and less time for her friends.  Miku is feeling alone and isolated, but she makes a promise with Hibiki to go get some snacks after school.  But when school ends, Hibiki gets another call...
If I'm fighting a person, not Noise...
...إذا قاتلتُ شخصاً، ليسَ من النويز
ich dann einen Menschen
und keine Noise bekämpfe,
Si peleo contra una persona 
y no contra un Noise...
Si peleo con una persona y no con un Noise...
Se invece il nemico è una persona,
e non un Noise...
Se minha oponente não for 
um Noise, for uma pessoa...
